[2.20] [4/6] Enumerate tests with special rules in tests-special variable


In order to generate overall summaries of the results of all tests in
the glibc testsuite, we need to identify and concatenate the files
with the results of individual tests.

Tomas Dohnalek's patch used $(common-objpfx)*/*.test-result for this.
However, the normal glibc approach is explicit enumeration of the
expected set of files with a given property, rather than all files
matching some pattern like that.  Furthermore, we would like to be
able to mark tests as UNRESOLVED if the file with their results is for
some reason missing (patch 5 does this), and in future we would like
to be able to mark tests as UNSUPPORTED if they are disabled for a
particular configuration (rather than simply having them missing from
the list of tests as at present).  Such handling of tests that were
not run or did not record results requires an explicit enumeration of
tests.

For the tests following the default makefile rules, $(tests) (and
$(xtests)) provides such an enumeration.  Others, however, are added
directly as dependencies of the "tests" and "xtests" makefile
targets.  This patch changes the makefiles to put them in variables
tests-special and xtests-special, with appropriate dependencies on the
tests listed there then being added centrally.

Those variables are used in Rules and so need to be set before Rules
is included in a subdirectory makefile, which is often earlier in the
makefile than the dependencies were present before.  The choice of
whether to include a given test is also often based on variables set
in Makeconfig, so includes of Makeconfig need to be added to some
subdirectory makefiles that didn't have them before (and that
previously just got it via the inclusion of Rules).

We previously discussed the question of where to include Rules; see
the question at
<https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, and a
discussion in
<https://sourceware.org/ml/libc-alpha/2013-01/msg00337.html> of why
Rules is included early rather than late in subdirectory makefiles.

I saw no reason why stdio-common had an indirection through targets
do-tst-unbputc and do-tst-printf rather than having the tests target
depend directly on the .out files.  Such indirections don't work for
generating test summaries - each test generating a .test-result file
needs listing in tests or tests-special - and so I removed that
indirection.  It was similarly necessary to avoid an indirection
through the check-abi target and get the check-abi-* targets for
individual libraries into the tests-special variable.  The intl/ test
$(objpfx)tst-gettext.out, previously built only because of
dependencies from other tests, was also added to tests-special for the
same reason.

The entries in tests-special are the full makefile targets, complete
with $(objpfx) and .out.  If tests were named consistently with a .out
suffix (I raised the question in path 2 of whether they should be
whenever output files are generated; there are also a few that don't
currently generate output files at all), then it would not be
necessary to include those elements in this variable.

Some questions arising from this patch:

* Should we define a rule that Makeconfig is always included by
  subdirectory makefiles immediately after they define subdir, whether
  or not they actually need an inclusion of Makeconfig, so they do not
  need to worry about whether conditionals on variables from
  Makeconfig can be used in a particular part of the file?  (If we do,
  then Rules would require that Makeconfig has already been included,
  rather than including it.  And various makefiles wouldn't need dummy
  "all:" targets because that in Makeconfig would always suffice.)

* If a test can only be run conditionally, the additions to the tests
  variable, or to dependencies of the tests target / the tests-special
  variable (before / after this patch), are conditional in the
  makefiles, but whether the makefile targets that say how to run such
  a test are also conditional varies.  This patch doesn't change such
  conditionals, but should we define a rule for whether such things
  are conditional (probably saying that the makefile rules aren't,
  just the additions to the relevant variable)?

* Should tests that don't generate output files be changed (in a
  separate patch or patches) to do so?

Tested x86_64.
